Abstract

A user of a graphical visualization program controls what data is selectable through the program interface. Data for display may be grouped and assigned an opacity value. The opacity value may correspond to the number of data points within an n-dimensional grouping, a particular type or other grouping parameter. Two or more data groupings may overlap within the interface. The visualization program may set a threshold selectability level, for example based on user input. The input may be received based on an selection threshold slide bar within a graphical portion of the display. When a user selects a data grouping at a point where two or more data groupings overlap, the data groupings that satisfy the threshold selection level may be selected. Data groupings that do not satisfy the threshold selection level will not be selectable.

Description

BACKGROUND

1. Field of the Invention
The present invention relates to visualization of data. In particular, the present invention relates to selecting data objects in an interface.
2. Description of the Prior Art
Visualization of data in three dimensional graphs can be helpful to understand the data. An example of a three dimensional graph is a plot of data on multiple axes, such as a horizontal, vertical, and another coming towards or away from the point of view of a viewer. Typically, visualization applications which display three dimensional data provide an interface having a graphical portion which provides data graphics and a control portion, such as a bar of control buttons. The control buttons may be implemented on a separate page from the graphical portion or otherwise separated from the graphical portion.
Many users desire to select different portions of data at a time to better understand data being visualized. However, it can be cumbersome specify which portions of a visualization should be selectable. What is needed is an improved visualization interface for selecting data as desired by a user.

SUMMARY

The present technology enables a user of a graphical visualization program to control what data is selectable through the program interface. Data for display may be grouped and assigned an initial selectability setting. The selectability setting may be based on nearly any aspect of the data, such as size, volume of data objects, color, property, value, opacity value, and so on. For example, when the selectability is based on opacity level, the opacity value may correspond to the number of data points within a multi dimensional grouping, of a particular type, or some other grouping parameter such that fewer data points in the grouping correspond to a lower opacity. Two or more data objects or groupings may overlap within the interface. The visualization program may set a threshold selectability setting, for example based on user input such as data ranges, threshold values, and other input. The input may be received based on a selectability slide bar within a graphical portion of the display. When a user selects a data object or grouping at a point where two or more data objects or groupings overlap, the data that satisfy the threshold selectability setting may be selected. Data that does not satisfy the threshold selectability setting will not be selectable.
For example, an initial threshold selectability setting may be set to select data groupings with at least ten data points. A selectability slide bar may allow a user to adjust the threshold selectability setting between a value of zero and one hundred. If the selectability setting is changed from the default of ten to fifty, data groups having less than fifty data points may be displayed but will not be selectable in the visualization interface.
An embodiment may perform a method for selecting data by displaying a plurality of data within an interface. Each data, which may include a point, object, grouping, or other data element, may be associated with a selectability level. Input may be received at a position within the interface associated with one or more data of the plurality of data. A determination may be made as to which of one or more displayed data within the interface satisfy a threshold selectability level.
An embodiment may include a system for displaying data. The system may include a processor, a memory, and one or more modules stored in memory. The one or more modules may be executed by the processor to display a plurality of data within an interface, each data associated with a selectability level, receive input at a position within the interface associated with two or more overlapping data of the plurality of data, and determine one or more displayed data within the interface satisfy a threshold selectability level.

DETAILED DESCRIPTION

The present technology enables a user of a graphical visualization program to control what data is selectable through the program interface. Data for display may be grouped and assigned an initial selectability setting. The selectability setting may be based on nearly any aspect of the data, such as size, volume of data objects, color, property, value, opacity value, and so on. For example, when the selectability is based on opacity level, the opacity value may correspond to the number of data points within a multi dimensional grouping, of a particular type, or some other grouping parameter such that the fewer data points in the grouping correspond to a lower opacity. Two or more data objects or groupings may overlap within the interface. The visualization program may set a threshold selectability setting, for example based on user input such as data ranges, threshold values, and other input. The input may be received based on a selectability slide bar within a graphical portion of the display. When a user selects a data object or grouping at a point where two or more data objects or groupings overlap, the data that satisfy the threshold selectability setting may be selected. Data that does not satisfy the threshold selectability setting will not be selectable.
For example, an initial threshold selectability setting may be set to select data groupings with at least ten data points. A selectability slide bar may allow a user to adjust the threshold selectability setting between a value of zero and one hundred. If the selectability setting is changed from the default of ten to fifty, data groups having less than fifty data points may be displayed but will not be selectable in the visualization interface.
FIG. 1 is a system for processing and visualizing data. The system of FIG. 1 includes structured data 110, unstructured data 120, application servers 130, 150 and 160, and data store 140.
Structured data 110 (RDMS data) may include data items stored in tables. The structured data may be stored in a relational database, and may be formally described and organized according to a relational model. Structured data 110 may be data which can be managed using a relational database management system and may be accessed by application server 130.
Unstructured data may include data that does not include a predefined data model or does not fit into relational tables as structured data 110. Unstructured data may include text, dates, numbers, facts and other data, including email, media and documents. Unstructured data may also include lists or other data associated with web page clicks, shopping cart data, and other data. Unstructured data may be accessed by application server 130.
Application server 130 may include one or more servers which receive and access structured data 110 and unstructured data 120. Filter application 132 may be stored and executed on application server 130, and may be executed to ingest the structured and unstructured data. Filter application 132 may apply filters, intelligence, or other processes to select a subset of the data received and/or accessed.
Data store 140 may include one or more data stores which receive data which has been filtered by filter application 132. Data stores 140 may include SQL servers, NoSQL servers, and other servers. The data may be stored in these servers until they are accessed for processing.
Application server 150 may include one or more servers which receive and/or access data stored in data store 140. Processing application 152 may be stored on application server 150. When executed, processing application 152 may access filtered data from data store 140 and analyze the data for trends, patterns, a particular data of interest, or other data desired for reporting. For example, processing application 152 may be implemented by “Apache Hadoop” software, which is an open source software application that provides a distributed application for analyzing data.
Once data is analyzed, visualization program 162 located on application server 160 may report the data to a user. The data may be provided in many forms, such as reports, visualizations, and other formats. For example, visualization application 162 may provide data in a three dimensional graphical visualization format. In some embodiments, processing application 152 and visualization module 162 may be implemented as part of a client server tool set for extracting data, mining data with analytical algorithms, and providing interactive visualization input.
FIG. 2 is a method for analyzing and reporting data. The method of FIG. 2 may be performed by the system of FIG. 1. First, structured data and unstructured data may be received at step 210. The data may be received by filter application 132 on application server 130. The received data may be filtered at step 220. Filter application 132 may filter the data by time sampling, applying intelligence, and other methods to result in a subset of the entire set of the received data.
Filtered data may be stored at step 230. The data may be stored based on the type of data it is. For example, structured data may be stored in a SQL database and unstructured data may be stored in a NoSQL database. The stored data may be analyzed at step 240. Analyzing the data may include looking for trends, patterns, or otherwise processing the stored data to determine a subset of data to report to a user. Analyzing the data may be performed by processing application 152 on application server 150. Once the stored data is analyzed, the data can be reported at step 250. The data may be reported through an interactive visualization, reports, or other methods that may be useful to a user. The visualization may present a multi-dimensional graph of data and allow data objects and groupings each associated with an selectability level to be selected based on a threshold selectability setting. Step 250 is discussed in more detail with respect to FIG. 3.
FIG. 3 is a method for providing a visualization of data. The method of FIG. 3 may provide more detail for step 250 of the method of FIG. 2. In embodiments, visualization application 162 may perform the steps of FIG. 3. The visualization application 162 may extract stored data, mine data for desired information, and provide an interaction visualization of the data.
Data to be visualized may be accessed at step 310. The data may be accessed locally or remotely, for example from data store 140. Data objects and groupings are identified at step 320. The groupings may be formed from data points (i.e., data objects) in multi-dimensional space, such that each grouping includes one or more data points that are within a threshold distance from each other in the multi-dimensional space. In some instances, in addition to location, groupings may be formed based on data values, data type, or other aspects of the data.
When identified, each data object and data grouping may be assigned a selectability value. The selectability value may correspond to a parameter of the data object or grouping and may control how the object is selectable. In some instances, the selectability of a data object or data grouping may be visually represented by opacity. For example, the opacity value for a grouping may correspond to the number of data points within the grouping.
In some instances, each grouping may be assigned a selectability level based on some other aspect of the data besides data volume, such as an entropy value for a bin of data, the number of data points per bin, a particular file in a record, color of the data, size of an object or grouping, or other data values. In some instances, the selectability may be associated with individual data points rather than bins of data, and selectability may relate to a particular field of each data point.
The data objects and groupings may be displayed within the interface of the visualization program with a default threshold opacity level at step 330. The threshold selectability level may control what data objects and groupings are selectable within the interface. For example, a default selectability setting may be set to ten. With this default setting, any data having fewer than a selectability value of ten (however that is determined, for example by a field value, volume, and so forth) would not be selectable in the interface. In some instances, the default may be user settable or saved as part of each particular visualization.
A determination is made as to whether input is received to adjust the threshold selectability level at step 340. The input may be received graphically, such as for example by sliding a selectability indicator along a selectability slide. An example of a selectability indicator that may be slid along a selectability slide is illustrated in FIGS. 4-6. If no input is received, the method of FIG. 3 continues to step 360.
If input is received to adjust the threshold selectability level, the threshold selectability level is updated based on the input at step 350. In some implementations, as the selectability indicator is adjusted, selectable data groupings or data objects may be modified. For example, a selectable data grouping in a collection of overlapping data groupings may be highlighted or otherwise modified with respect to their representation in the interface.
In some instances, the input may be received as moving a slider along a bar. A “splat” or other graphical representation of data may be displayed next to the slider, for example to the left, right, top or bottom of the slider. As the slider is moved along the bar to select a different selectability level, the splat will move with the slider and change selectability. Thus, when the slider is at one end of the bar, the splat will be displayed next to the slider and have a first value that represents a selectability threshold set by the particular position of the slider. At the other end of the bar, the splat will be still displayed next to the slider, at the slider's new position, and have a new value that represents a selectability threshold set by the new particular position of the slider.
A determination is made as to whether input to select a data grouping or data object is received at step 360. If no input is received, the method continues to step 380. If input is received at step 360, data that complies with the threshold selectability level is selected at step 370. The input may be received at a particular point in the interface, for example at a point selected by a cursor. In some instances, when two or more data groupings or objects are overlapping at the selected point, only a data object or grouping that includes the selected point and satisfies the threshold selectability level may be selected. For example, if a threshold selectability level is set to fifty, a first data grouping has an selectability level of thirty, a second data grouping has a selectability level of seventy, and both the first data grouping and the second data grouping cover a particular point in the interface, the second data grouping will be selected in response to user input selecting the particular point in the interface that overlaps both data groupings. After selecting the appropriate data grouping at step 370, the method continues to step 380.
A determination is made as to whether the input is received to display a particular data type at step 380. In some embodiments, input may be received to display data having a certain data filed, certain data values, data from a particular source, or data having some other aspect or parameter. The input may be received via a slide bar, such as for example that shown in FIGS. 7-8. If input is not received to display a particular data type, the method of FIG. 3 returns to step 330. If input is received to display a particular data type, then the graphical display is updated based on the data type input at step 390. In some embodiments, the data types displayed may be updated to display only the selected data type. In some embodiments, the data type may be updated to display all data types except the selected data type. The method of FIG. 3 may then continue to step 330.
FIGS. 4-6 illustrate examples of a visualization interface for displaying multi-dimensional data. FIG. 4 is a visualization interface having a selectability slide. The interface of FIG. 4 may include selectability slide 510 and data groupings 520-544. Selectability slide 510 includes selectability indicator 512 and selectability level indicators 514, 516 and 518. Selectability level indicator 514 is associated with a range of selectability values associated with data groupings 520, 522, 524 and 526, selectability level indicator 516 is associated with a range of selectability values associated with data groupings 530, 532, 534 and 536, and selectability level indicator 518 is associated with a range of selectability values associated with data groupings 540, 542, and 544. Selectability indicator 512 may be moved along selectability slide 510 to set a threshold selectability level. The slide may be used to determine what data groupings are selectable within the interface based on threshold selectability setting.
In the interface of FIG. 4, a cursor 560 is positioned to select a point within the interface of FIG. 4. The point, located at the tip of the cursor, is at a position where three data groupings— data groupings 526, 536, and 542—overlap. The selectability indicator is set to a value below selectability level indicators 514, 516 and 518. As such, all data groupings and objects associated with those indicators will be selectable. As a result, the data grouping at the top of the overlapping data groupings will be selected at the point associated with cursor 560. In FIG. 4, this corresponds to data grouping 526, which is highlighted in the interface of FIG. 4.
FIG. 5 is another example of a visualization interface having a selectability control bar. In the interface of FIG. 5, the selectability indicator 512 is set below the selectability level indicators 516 and 518 but above selectability level indicator 514. Data groupings and objects having a selectability level less than selectability indicator 516 will not be selectable in the interface of FIG. 5 based on the threshold selectability level set by indicator 514. In particular, data grouping 526 is not selectable and cursor 560 may be used to select the next highest data grouping at the point of the cursor—this corresponds to data grouping 536, which is highlighted in the interface of FIG. 5.
FIG. 6 is another example of a visualization interface having a selectability control bar. In the interface of FIG. 5, the selectability indicator 512 is set below the selectability level indicator 518 but above selectability level indicators 514 and 516. Based on the indicator level, the threshold selectability level set by the indicator would prevent data groupings 526 and 536 from being selectable (these data groupings have selectability levels associated with selectability level indicators 514 and 516). Though they encompass they point selected by cursor 560, data groupings 526 and 536 are not selectable because they do not satisfy the threshold selectability level. Therefore, data grouping 542 would be selected by cursor 560 in the interface of FIG. 6.
In each of FIGS. 4-6, a single slider is used to control the selectability selections. This is intended as an example only. A visualization interface of the present technology may have one or more sliders to control selection based on selectability or any other property, for example to allow selection within a narrower range of values.
In some instances, the selectability sliders may control data ranges for columns not represented in the visualization. For example, in a car data visualization, a slider may set a range such that 2010-2015 models are selectable, even though model year isn't mapped to anything in the visualization. Conversely, the selection range sliders could represent columns that are mapped to visual parameters, such as color ranges (where, e.g., color represents mpg) or size ranges (where size represents # cylinders).
FIG. 7 is a visualization interface having data type selection buttons. The interface of FIG. 7 includes data groupings 520, 524, 534, 536, 542 and 544, data type slide 710 and data type indicator 720. The data type indicator 720 may be moved across slide 710 to select different types of data to be selectable (or not selectable). For example, the values for X, Y, and Z illustrated near the slide in FIG. 7 may be 0.1, 0.5, and 1.0, respectively. In FIG. 7, data type indicator 720 is set to a first position. While at this position, data groupings 520, 524, 534, 536, 542 and 544 associated with that type of data are selectable. FIG. 8 is another visualization interface having data type selection buttons. In FIG. 8, data type indicator 720 is set to a second position. While at this position, data groupings 522, 526, 530, 534, and 540 associated with that of data are selectable.
In some instances, the present technology may be used to set selectability thresholds based on any data range, including but not limited to data mapped to opacity. For example, the present technology may display data in all different colors and sizes, but set multiple selection range sliders to only allow the user to select medium-sized red data objects. In some instances, a selection threshold may be set for an attribute with no graphical mapping at all, just using data ranges that may be in the data. The present technology may also be used to fade in or out the unselectable data or highlight the selectable data, if it made it easier to see whether the selection thresholds were set correctly.
